❓ Frequently Asked Questions
How does the led strip power calculator work?
Enter your LED strip length, its watts per meter, and a headroom margin to get the total load and the power-supply wattage you should buy.
Is the result exact?
It's a planning estimate using standard lighting rules of thumb. Real figures vary with the specific product, fitting, and conditions, so check the manufacturer's specification for an exact value and treat this as a starting point.
Can I wire the power supply myself?
A plug-in adapter goes in by its instructions. A supply or driver wired into mains power, in a wall, ceiling or cabinet, is electrical work that in many places must be done by a licensed electrician. Use a supply rated for the strip's voltage, keep it ventilated, and never load it past its rating: the result is rounded up to a whole watt for that reason, and the next standard size up is the one to buy.
